Antalpha interview questions

I was approached by the HR and then was booked an interview afterwards. The interviewer is the rudest I have ever seen. The person would not turn on a web cam and was rushing through the process. He dashed through was supposed to take him 30 minutes with 5 minutes of question shooting and was super impatient. Honestly, if you are unhappy with my profile, might as well cancel the interview. A waste of both of our time that lacks basic decency and professionalism.
